.chines, of which the following is a specification.

This invention relates principally to type-- writing mach nes forwriting upon a number of superposed webs or continuous sheets,especially those which are intended to be torn off in sections from thebody of the web, as, for example, when the webs comprise a series ofprinted forms, each adapted to be removed when the typewriting thereonis completed. In'such work it is desirable to employ ink ribbons orcarbon sheets interleavedwith the webs for making the duplicate copies.In the use of such carbon sheets practical difficulties are encountered,especially in round-platen machines, in removing the carbon sheets fromthe portions of the webs that have been written upon, and shifting themto new positions for writing upon the succeeding portions of the webs.These diiiiculties are due partly to the fact that the webs have topursue a tortuous course in passing through a round-platen machine,causing the carbons to be bound between the plies of web.

One feature of the present invention is the provision of practical meansfor releasing the carbons from the binding action of the webs thereon,and for withdrawing or pulling back the carbon or inking sheets, priorto the writing of the succeeding page or form, and bringing all thesheets into proper position to write thereon.

In carrying out certain features of our invention in one form, theround-platen type- I writing machine may comprise an auxiliary s'upportor carrier, attached to the-usual letter-feeding platen carriage totravel therewith, and extending rearwardly or backwardly therefrom. Thecarbon sheets or ink ribbons which are interleaved with the continuouswebs may be attached} at their rear ends to a holder slidably mounted onsaid auxiliary carrier, to permit the car- -l)on sheetsto be fed forwardaround the platen. with the continuous webs, and to When the retract thecarbon sheets or shift them rearwardly along the webs of paper into anew position, for writing the next page.

The platen is mounted on a swinging frame on the platen carriage, sothat it may be lifted from the platen feed rolls and permit the webs andcarbon sheets to be brought aboutto a straight line position, or atleast to be sufliciently straightened out to release the frictionbetweenthe carbon sheets (or ribbons) and the webs, and to permit the carbonholder to be automatically retracted'by means of a spring. The swingingframe in which the platen is mounted may comprise a rock shaft journaledin the ends of the carriage frame and carrying rock arms in which theplaten axle is jour naled.

In order to permit the platen to be rotated by the usual line-spacemechanism or hand wheel, a platen rotating shaft, which in the presentinvention is separate from the platen axle, is journaled in the endofthe carriage frame and provided with a linespace ratchet wheelforcontrol and operation by the usual spring detent, and the usualline-space lever and intermediate mechanism.- The rotation of said shaftis transmitted to the platen through a train of gears comprising gearwheels connected to the platen axle and the line-space wheel shaftrespectively, and normally lying side by side, said gear whe'els bothmeshing with a pinion, which may be mounted on the rock shaftwhich formsthe axis of the swinging platen frame. A permanent coupling ordriving-connection is thus maintained between the line-space wheel andthe platen, and the latter is permitted to be swung or displacedupwardly away from the pressure rolls, both to release the work sionthereof, is provided with an adjustable gage to which the forward endsof the webs are brought, in advancing the webs to position for writingupon a succeeding form. typewriting upon one form has been completed,the platen-swinging frame is swung upwardly by a handle thereon, therebyseparating the platen from the work pieces and releasing the carbonsheets or ribbons, permitting the carbon holder to be drawn rearwardlyunder the influence of its operating spring, thereby shifting the carbonsheets back to a new position between the succeeding work-forms on thewebs. The swinging of the frame to lift the platen also swings saidpaper shelf to a substantially horizontal position, in line with thecarbon sheets and webs at the rear of the platen, thus assisting infreeing the carbon sheets. The operator may then grasp the ends of thewebs and pull them forwardly to said gage. The platen is then swung downto writing position, and the completed forms may be severed by a knifeblade, which may extend along the platen above the printing line, andwhich may be swung against the platen to permit the webs to'be severed.

The holder for the carbon sheets or ribbons when automatically retractedas above noted, may be brought to such position that the forward ends ofthe carbon sheets extend up beyondthe printing line to within a shortdistance of the line along which the workforms are severed.

Other features and advantages will hereinafter appear; and many featuresof this invention may be used for other purposes, and eitherseparatelyor in combination with others.

In the accompanying drawings, Figure 1 is a perspective view of ourinvention applied to an Underwood typewrlting mach ne, the parts beingin position to permit writ ng upon a work-piece. Fig. 2 is a similarview showing the swinging frame thrown forward and the platen therebylifted to release the webs and the carbon sheets. Fig. 3 is afragmentary end elevation view showingthe platen in position forwrit-mg. Fig. 4 1s a similar View but with the laten swung upward. Atthis figure the eed rolls are diagrammatically illustrated as swung downward to an inoperative position in the usual manner. Figs. 5, 6, and 7are diagrammatic views illustrating the method of removing a completedbill or other workpiece with its duplicates, and positioning asubsequent work-piece. Fig. 5 shows the normal posi tion of parts whenthe writing upon a bill or other work-form has been completed. Fig. 3shows the platen'displacing frame swung forward to lift the platen, andthe carbon sheets which have thereby been released moved rearwardly to anew position. Fig. 7

shows the platen-swinging frame swung back to return the platen tonormal position, and the completed forms partly severed by the knifeblade.

T he rotary platen 1 is carried by the usual carriage 2, which may bedriven in letterfeed direction by the usual spring motor, and itsletter-feed movement controlled by the usual mechanism, not shown. Thecarriage usually comprises a front bar 2 and a rear bar 2. Type-bars 3operated in the usual way, swing upwardly and rearwardly against thefront face of the platen. Each type-bar may carry two types, and theplaten may be shiftable up and down to different writing positions inthe manner usual in the Underwood machine. Front and rear feed rolls 4and 5 which run on the under surface of the platen or work-piecesthereon, are mounted on shafts 6 supported in levers 7 journaled on arod 8 forming part of the usual shiftable platen frame. Said feed rollsmay be lifted from the platen by the usual finger key 9 connectedthrough a link 10 to an arm on arock shaft 11 formed with flats or camsurfaces 12 which engage arms 13 of the levers 7.

The present invention is particularly usefui in connection with a seriesof continuous webs or strips of paper 14:, superposed and interleavedwith carbon sheets or ribbons for making duplicate copies. The webs 1imay each consist of a continuous series of printed forms, and may besupported'on an auxiliary carrier or framework located behind the platencarriage 2 and connected to travel therewith. Said auxiliary carrier orframe work, as shown, comprises side rails 15 in the forin of channelirons extending in a substantially horizontal direction rearwardly fromthe carriage 2 perpendicular to the platen, said rails connected bytie-rods 16 and 19. The rod 16 is supported on arms 17. which, as shown,are secured to the bar of the carriage against which usually rests therear face of an inclined paper table 18 at the rear of the platen, whichtable may form part of the usual case-shifting platen frame.

The auxiliary carrier may be supported at its outer end by a framecomprising side bars 20 rigidly connected at their forward ends to themachine frame 21, and at their rear ends-connected by a rail 22 on whichruns a roller 23 mounted on a cross bar 2% 5 edges of the webs.

The invention is also useful with separate superposed webs; and eitherthe superposed separate webs or the fan-folded webs may be convenientlysupplied from one or more spools or rolls, as 25. In order to duplicatethe typewritten matter on the several wehs or plies 14. duplicatingmaterial, such as ribbons or carbon sheets 27, is provided, said sheetsbeing interleaved with the webs 14, and connected to a carrier orshifter in the form of a truck 28 mounted to travel on the rails 15toward and from the platen. The truck 28 comprises a sheet metal body29, which may also form a support for the Webs, and ends 30, which carryrolls 31, running in the channel rails 15.

Holding bars or fingers 32 for the carbon sheets 27 are seated in theends 30 of the carrier and removably secured in position by thumb screws33. Each bar or finger 32 extends nearly across the frame, the free endof the bar permitting the carbon or inking sheet to be readily placedthereon or removed, such sheet being preferably provided with a loop atone end to slip over the supporting bar 32. These bars or fingers may beconnected alternately to the opposite ends 30, as desirable to permitthe carbon sheets to be slipped between adjacent plies of web 14 whensaid web is formed of a single fan-folded sheet. The bars 32- areseparated, preferably by being stepped, as indicated, to properly spacethe carbon sheet holding fingers one above another, for introductionbetween separate plies of the fan-folded Web, and said bars or fingersare also preferably arranged one behind another, for clearance. andconsequent convenience in attaching the inking sheets separatelythereto. The webs 14 may be spaced and guided at the rear end of thecarriage by fingers 34 adjustably attached to the rails 15. Gages 35 forthe side edges of the webs 14, and forming part of the web course at theintroductory side of the .machine, may be adjustably secured to a bar 36connecting the ends of the rails 15, said gages being adjustable alongsaid bar to accommodate webs of different widths.

During the typewriting operation of the machine, the carbon sheets whichextend forward between the platen and feed rolls,

are fed forward with the webs, the carbon holder 28 being pulled forwardalong the guide rails 15 as the webs are advanced.

In order to automatically return the holder or shifter 28 when thecarbon sheets are released by separating the platen and feed rolls, ashereinafter described, a spring motor 37 is connected through a band 38to the holder 28. The band 38 is connected at one end to the carbonholder and extends therefrom to and around a pulley 39, yvhich may besupported on the rail'36, and from said pulley the band extends forwardto a drum 40 of the motor 37. Said drum is mounted to rotate on a shaft41, which is journaled in arms 42 depending from the tie-rod 16. Thedrum 40 is always under tension, provided by coil springs 43 eachconnected at one end tothe drum and at the other end to the shaft 41.Said shaft is held against rotation by a ratchet wheel and pawl 44, 45,the ratchet wheel being fixed to the shaft. A hand crank 46 permits theshaft to be rotated to adjust the tension of the springs 43.

Thenthe carbon sheets are released from the platen and feed rolls, thedrum 40, under the tension of the springs 43, rotates to wind the band38- thereon and draws the carbon sheet holder 28 rearwardly to the outerend of the rails 15, thereby shifting the carbon sheets back to a freshpage or portion of the webs 14.

The platen 1 is mounted for upward displacement in a swinging sub-framecomprising arms 47 in which the platen axle 48 is journaled, said armsbeing fixed to a rock shaft 49 journaled in the ends of the shiftableplaten frame 18 which is mounted on the paper carriage 2, so that theplaten may be swung upward away from the feed rolls 4 and 5, and abovethe front and rear bars 2 and 67, between which the platen normally issunken, in order to permit the opening out of the web, which runs intothe machine about horizontally along a course comprising parts 34, 35,32, 28, and 67, thence tortuously down around the platen and upwardlytherefrom, whereby the inking sheets are normally clamped or boundbetween the plies of web. The pressure rolls 4, 5 also tend to lock theinking sheets to the web.

In order to rotate the platen either by the line-space mechanism or ahand wheel 50, a platen-rotating shaft 51, which isseparate from theaxle 48 but which may normally be in line therewith, is journaled in theplaten frame end 52, and drives the platen through a train of gearscomprising 'a gear wheel 53 fixed to the shaft 51, and a gear wheel 54fixed to the platen axle 48, said gear wheels both running inmesh with apinion 55, which is journaled on the rock 'wardly inclined position(Fig. 3) and is locked in such position, together with frame 47, 49, bya sprng latch 60, which engages a holding pin 61 on the arm 58.

The platen-displacement frame also comprises a web-supporting andguiding shelf 62whic'h may be rigidly secured to the arms 47, andnormally extends upwardly and 'rearwardly from the delivery side of theplaten. A bar 63 forming an extension of the shelf 62, and supportingand guiding the leading ends of the webs as they are advanced, alsoforms a support for an adjustable gage 64, the latter secured to the bar63 at anypoint by a. clamping screw 65. Gages 66 for the side edgesof'the webs are slidably' mounted on the shelf 62 and .are frictionallyheld in any position to which they may be adjusted longitudinally of theshelf.

In operation, the webs 14 are guided-between the fingers 34 and gages 35and extend forward over the carbon holder 28 and are guided over bar orroller 67 at the upper end of the paper table 18 and from thence extenddownward between the platen and feed rolls, thence upward over the frontface of the platen past the printing-line and I over the shelf 62. Asthe typewrlting protween 2, 67, to the Fig. 6 position, above.

2*, 67. The'shelf 62 may now be substan tially horizontal andapproximately in line .with the'portions of the webs behind the platen.

Thus the web is opened out, for

convenience in manipulating and adjusting,

and for releasing "the ink sheets. When the handle 59 is swung forward,the ends of the v webs 14 are grasped by the operator and pulled forwardto the gage'64,- where they may be gripped between the operators.thumb'and the bar 63. As the platen is lifted to the Fig. 6 position,the carbon sheets,

which up to this moment have been held between the platen and feedrolls, are released and the spring-drum 4O permitted to rotate and drawthe carbon sheets rearwardly, as heretofore explained, to the Fig. 6position.

' It will be observed that in the'Fig. 6 position, the webs being in asubstantially v straight line, will not bind on the carbon sheets orhinder their withdrawal. The

platen-displacement frame may then be returned to the Fig. 7 position,and the webs 14 and the carbon sheetslagain gripped between the platenand feed rolls, ready for writing upon the succeeding form. The

bills or work-forms which have just been completed are now severed bymeans of a tearing blade 68, extending along the upper surface of theplaten and mounted on a rod 69 (which may be a sleeve on the shaft 49)to be swung downward against the webs by means of a finger-piece 70,said blade being returned by a spring 71. In Fig. 7 the blade is shownin tearing position, and the webs partially severed.

It will be noted that, as shown in Figs. 5 and 7, the carbon sheets donot extend to the ends of the webs 14, so that the operator may graspthe webs without holding the carbon sheets or interfering with theirautomatic retraction. The carbon sheets,

however, are of sufficient length to extend upwardbeyond the printingline when the platen has been returned.

As the platen frame is returned from the Fig. 6 to Fig. 7 position thewebs 14 are curved over the platen surface and hug the platen so thatthe ends of the carbon sheets are gripped between the webs and carried.with the platen, as the latter rolls back to printing position. Whenthe feed rolls l and 5 are moved ofi the platen by depressing thefinger-piece 9, the platen s held from dropping below. normal pos t onby the latch 60. A stop pin 72 at the right hand end of the swingingplaten frame m the path of said frame forms a rigid stop for theright-hand end of the platen-to prevent it from dropping below normalposition.

Variations may be resorted to wlthm the scope of the invention, andportions of the improvements may be used without others.
